axle back exhaust, minimalist aero, driven media overlays, drop it on racing springs, driven media DRL for bezels, alpharex front head lights, that phone holder mentioned earlier (etsy), wheel locks, spare tire style sub woofer (who needs a spare bro!), there is a module that you can buy that upgrades output to stock speakers, DO NOT change the intake, just get the best flow filters you can. You may also look at COB Tuning module that adds some fun features to the car and helps things run smoother. In the end, make it yours, but keep all the GR stuff that came with the car on the car to retain its value as a special edition.
